Manuscript Summary: This collection of cosmological treatises contains excerpts from a larger manuscript, presumably written by the same scribe Moses, which now is part of the Schoenberg Collection at the University of Pennsylvania in Philadelphia (ljs 057).
The manuscript contains tables on lunar motion by Jacob ben David Jomtow (Bonjorn); three astrological works by Abraham ibn Ezra (1089 - about 1164): a fragment of Reshit Hokhman ("Beginning of Wisdom"), the larger part of Mischpetei ha-Mazzalaot ("Judgments of the Constellations") and the larger part of Sefer ha-Olam ("Book of the World"); and, as the last part the Sefer ha-Mivharim le-Batlamyus, i.e. Ptolemy’s "Almagest".
On f. 15r and f. 15v there are three images of constellations from classical antiquity: Orion (Ha-Gibbor ba-Te’omim, "the hero of twins") in bare feet and with a scimitar (f. 15r), Eridanus (Ha-Nahar, "river") and Lepus (Ha-Arnevet, "hare") (f. 15v). The imagery is based on the Arabic "Book of Fixed Stars", written in 964 by the Persian astronomer Abd al-Rahman al-Sufi. (red)
